28-year-old Latrice L. Foster pleaded not guilty to child endangering.
The little boy fell from the window last Thursday while in the care of his 3-year-old sister. Neighbors tell 19 Action News they saw the child's mother leave an hour before the incident, and this wasn't the first time she'd left her kids home alone.
The toddler was taken to University Hospital Rainbow Babies and Children's Hospital, where he was treated and released.
Foster's bond was set at $5K dollars.
